SPECIFICATION forming part of Letters Patent No. 730,448, dated J une 9, 1903. Application led March 18, 1902. Serial No. 98,795t (No model.)

To @ZZ whom it' may concern.-

Beit known that I, JOHN FERN, a citizen of the United States of America, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Conveyors, of which the following is a specification.

This invention relates to conveyors, andis designed for use in directing deposits to a main conveyer, in conjunction with which it operates.

The object of the invention is to produce a conveyor which can be moved in an arc for the purpose of carrying material, the said conveyor being moved over the deposit to dislodge the same. Y

The invention is of unusual importance in connection with the transfer of culm, which is generally found in large banks'of considerable length. In reclaiming coal from culm la fixed horizontal and inclined conveyer is constructed,which delivers culm to a washer. The auxiliary conveyer, which comprisesthe present invention, is transferable along the iixed conveyer and acts on the receding sur.- face of the bank at any desired angle, dislodging and carrying the culm-to'the main` conveyer.

Furthermore, the object of the invention is to provide means whereby the auxiliary conveyer may be moved from one position to another throughout the length of the main con-A veyers.

produce conveyers of the `character notedl which will possess advantages in points of simplicity, efficiency, and durability, proving at the same time comparatively inexpensive.

' With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts, to be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, Wherein like characters denote corresponding parts inthe several views, and invwhichff Figure 1 is a plan view of a xed convey'er trough and frame with the auxiliary conveyers applied. Fig. 2 is a sectional view on the line X X of Fig. 1 with the yoke and auxiliary conveyor in elevation. Fig. 3 is an enlarged detail view of the auxiliary gearing. Fig. 4 is a plan view of a modified auxiliary conveyor and power-shaft. Fig. 5 is a detail view ofthe journal-bearing. Fig. 6 is a view in elevation of the parts 15 15 l5h detached from the conveyor. Fig. 7. is an end View thereof. l Fig. Sis a sectional View of a portion ofthe yoke, showing the split bearing. Fig. 9 is an enlarged detail View of the hoisting device. Fig.`10 is a detail view, partly in section.

In the drawings, 1 denotes the frames of the fixed conveyer, which support the T-rails 2.

A'plate 3 has au arm 4, which is secured to one of the T-rails 2 by means of the clamp The plate projects beyond the edge of the frame l and is cut away to'receive the drum VA6 and ratchet-Wheel 7.

Bearings are formed in the plate 3 forthe shaft' 8, on which the dru m and ratchet-wheel are mounted. Plates 9 form-theupper halves of the journal-bearings and are bolted to the plate 3, the. said plates 9 having bent-up ends whichl lie over the base-flange of the T-ral for supporting the plate- 3. A flexible shaft lO is journaled in the bearings 11, secured to the uprights of the frame of the main conveyor, and I have found in practice that wire cable which has become worn in use for hoisting purposes may be utilized to advantage as a flexible shaft. A yoke 12 is pivoted on the hub 15 and has a supporting connection 13, which is wound on theA drum. Bearings are formed in the yoke for the short shafts 14, and gear-wheels l5 on the iiexible shaft mesh with the pinions 16 on the short shafts. The wheel15 has an extended split hub 15a, terminating in a clip 15, by which the wheel is clamped to the shaft. The hub, between the wheel and clip, forms a pivot for the yoke.

One member of a universal joint 17 is secured to each of the short shafts 14', and the IOO,

opposite members of the universal joints are connected to the shafts 1S of the conveyerscrews 19. It will be observed that the power applied to the flexible shaft will be transferred to the auxiliaryconveyer screws through the gearing just described.

Blocks 2O are loose on the outer ends of the shafts 18, pulleys 21 are mounted in recesses ot' the blocks, and ropes 22 or other flexible connections are employed to cause the ends of the shafts to approach each other, while other ropes 23 are employed to draw the shafts apart. By means of the ropes, properly manipulated, the conveyers may be oscillated from side to side over a culm bank for the purposes heretofore stated. Y

A chute 24 has ears 25, which are pivotally connected to the lugs 2b' of the yoke through the medium of the pins or bolts 27, and as the yoke is adjusted vertically or longitudinally of the shaft the chutel is carried to act in conjunction with the auxiliary conveyers for delivering to the fixed conveyer.

Under certain conditions, and especially where the auxiliary conveyers need not be moved longitudinally of the fixed conveyer, the device illustrated in Fig. 4 may be employed. In this device the yoke 12 is employed; but I may use a series of rigid shafts connected by universal joints A. Frames B are pivoted to lugs 26 of the yoke, said frames being in sections connected by universal joints C to permit a given movement of the frames. Conveyer-shafts D are supported by adjustable bearings in the ends of the frame and are connected by universal joints with gearing similar to that shown in Fig. l, except that the gearing is driven bya shaft comprising rigid sections instead of the flexible shaft.

When it is desired toy move th'e auxiliary conveyer along the main conveyer, the ilexible shaft is released from the bearing 1l and sprung out a suicient distance to permit the yoke and gear-wheels to pass the upright members of the frame of the fixed conveyer. The yoke 12 is also moved along the shaft 10, the clips l5b being loosened to permit said yoke to'slide on said shaft 10. The yoke-elevating mechanism is also removable by disengaging the clamp 5, as will be apparent.

The swinging journal-bearing l1 is pivoted on the plate at, which is attached to an upright member of the conveyer-frame, said plate being bent in a recess of the upright. A guide b is secured on the lower end of the plate a and serves to prevent outward movement of the bearing, said bearing consisting of two members d, pivoted near the top to the plate a, as shown in Fig. 5.

The construction, operation, and advantages will, it is thought, be understood from the foregoing description, it being noted that various changes may be made in the proportions and other details of construction for successfully carrying the invention into practice. l

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isy l. In a device of the character described, a main conveyer, auxiliary conveyers radiating from the main conveyer, a liexible shaft by which the auxiliary conveyers are driven, the said parts being so arranged that the auxiliary conveyers may be moved longitudinally of the flexible shaft, as and for the purpose described.
